Struct gstreamer_editing_services::Project [−][src]
pub struct Project(_);
The crate::Project is used to control a set of crate::Asset and is a
crate::Asset with GES_TYPE_TIMELINE as extractable_type itself. That
means that you can extract crate::Timeline from a project as followed:
GESProject *project;
GESTimeline *timeline;
project = ges_project_new ("file:///path/to/a/valid/project/uri");
// Here you can connect to the various signal to get more infos about
// what is happening and recover from errors if possible
...
timeline = ges_asset_extract (GES_ASSET (project));
The crate::Project class offers a higher level API to handle crate::Asset-s.
It lets you request new asset, and it informs you about new assets through
a set of signals. Also it handles problem such as missing files/missing
crate::gst::Element and lets you try to recover from those.
Subprojects
In order to add a subproject, the only thing to do is to add the subproject to the main project:
ges_project_add_asset (project, GES_ASSET (subproject));
then the subproject will be serialized in the project files. To use
the subproject in a timeline, you should use a crate::UriClip with the
same subproject URI.
When loading a project with subproject, subprojects URIs will be temporary
writable local files. If you want to edit the subproject timeline,
you should retrieve the subproject from the parent project asset list and
extract the timeline with crate::prelude::AssetExt::extract() and save it at
the same temporary location.

Implementations
impl Project[src]
impl Project[src]pub fn new(uri: Option<&str>) -> Project[src]
pub fn new(uri: Option<&str>) -> Project[src]Creates a new crate::Project and sets its uri to uri if provided. Note that
if uri is not valid or None, the uri of the project will then be set
the first time you save the project. If you then save the project to
other locations, it will never be updated again and the first valid URI is
the URI it will keep refering to.
uri
The uri to be set after creating the project.
Returns
A newly created crate::Project
